Chinese Govt orders Nikon to stop selling D600(mid-March).(post no.136)..

The Chinese Government has issued an order to Nikon to stop the sale of D600 in the country. This move was made following an investigative report by China Central Television (CCTV) which showed dealers refusing to refund the money to unsatisfied customers. The camera had issues with dust and spots. The company had recently released the D610, which had the same features but eliminated the faults of the D600...............I think the dealers shd hv been cooperative with the not refund the money but, if possible, get the problem solved.....Nikon must hv good Nikon cameras repairing shops in China........It is a matter of consideration for us, that Govt thinks of its citizens in this small issue.....

Noise/Grains in DCAMs. (post no.135).Matter of quality.


The photo uploaded here is shot with a compact dcam at ISO 400, which inevitably shows the grain when enlarged to 100%. The face of my grand son I picked up from the whole image. The details look merged. My point here is that in compacts if we go above ISO 200, the noise appears. The compacts are sold more, as they are aimed at general public photography/ enthusiasts/beginners However, if you use prosumers, even the problem of grain at ISO 200 may be started showing. In DSLRs, this problem will arise at ISO 800 and above. During film days the photographers generally got the film rating at ISO 100 for most purposes and for professionals ISO 200 and 400 were readily available in small towns too. So most of photographers used ISO 100 film and got best results and enlargements in weddings, travels and all functions, with good sunlight and bright shadows or indoor or outdoor with good brands of powerful flashguns....Though a bit difficult in low light, unless tripod is used.
The improvement I made in the image by denoising and slight sharpening it, so my worry of getting a grainy/noisy pic is reduced
and I can get a good enlargement of the full image shot on the small sensor of a compact camera....The sensor size is the main issue of having noisy results because of the compactness/thinness of the small cameras. SO IF YOU shoot with a compact, shoot at the minimum noise level set by the manufacturer i.e. may be ISO 80 or 100. The pros who use DSLRs are aware of the problem and therefore set and shoot according to their requirements in those cameras almost at ISO 100 or ISO200 FOR FINE DETAILS and sharpness in images...................YES there is cost difference in compacts, prosumers and DSLRs. Therefore interest in photography go accordingly from person to person and their requirements.

Back light in Photography-portraits.(post no.134).

-Contre-jour/Against the light/Back light.....Light from u may call it....but it has enormous potential for any subject, especially portraits, may be in Studio, outdoors.....This automatically detatches your subject from the background, giving it its own identity....Ours is a country having sun round the year.Shooting back-lighted subjects is well done in morning and evening. However, there are grt opportunities to be shot even during day time as the sun is at an angle in 'winter' season.

--Exposure calculation is easy. For example, if u use outdoors an aperture of f11 in frontal lighted subjects, the shutter speed may be 1/500 to 1/1000 as per intensity of light at ISO 100.....When shooting against light, use lens hood,  watch light and increase aperture by 1 to 2 stops. U can easily view the result on camera screen and make necessary changes, if need be.

--When in studio shooting backlight, u can have more good effect with a side, or both sides flash/strobe lights and a light on the background too....As experiments are done we achieve unexpected results with our male or female subject, may be children too.
